Hold command, option, p, r on the keyboard. That will reset a Mac, BackTrack not needed.

Of course, if you really wanted to have some fun, go to Wal-Mart late at night and ask the greeter if they could help you find trashbags, roll of carpet, rope, quicklime, clorox and a shovel. See if they give you any strange looks. --Streaker69

Try unloading and re-loading the driver of the card, it at least should reset the MAC address back to the default one. The driver will depend on which wireless card you have but for example for the Alfa 500mw the following should do the trick:

Code:

rmmod r8187
modprobe r8187

If you are using an USB connectable card you can also simply pull it out and re-insert it. If you remember the default MAC address you can also use macchanger to change back to the old one, for example:

macchanger --mac 00:11:22:33:44:55 wlan0

Unless you own a Macintosh you do not have them.

I've like to do that without unloading the driver.
Also can I change mac without going ifconfig down? cuz I always hear ifconfig down first then mac then ifconfig up again.

May I ask why? But in that case if bringing the interface down, as already suggested, simply use macchanger to set it to the default MAC or simply reboot BT3.
Will depend on your wireless card. Why not simply try it out for yourself instead of posting a question?

reboot takes time and I can reset the mac manually but I wanted to do it automatically like in windows.
